stream filter: add "no more input" to the filters
Some filters may need to buffer the input and look-ahead inside it to decide what to output, and they may consume more than zero bytes of input and still not produce any output. After feeding all the input, pass NULL as input as keep calling stream_filter() to let such filters know there is no more input coming, and it is time for them to produce the remaining output based on the buffered input.
